If you open the 3DS all the way pass the click, it should look like that.

Correct, though I strongly suggest not doing this, ever, as it was the cause of the hinge problems on the DS lite.

I used to do this for fun on my Lite and it's not even developed a hairline crack. I may be in a minority it seems. I wouldn't expect this to happen with the 3DS or at least not most of them as it seems the hinge is better designed and looks more sturdy.

You do not need to open the 3DS like that. Is this your first DS system?
Both screens do not to be lined-up. You're suppose to just open it up to an angle.
Just see the front page of this site (3DS recap topic) to have an idea on how it should open.
(Maybe I just got trolled...)
